noon-HOLDING DEVICE.

Application m m e 1925. Serial No. 14,000. I i

To all whom it may concern Be it known that I, EMIL OLSON, a citizen of the United States, residing at South Haven, in the county of WVright andState of Minnesota, have invented certain new and useful Improvements in Door-Holding De.-

vices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a door holding means and while the invention may be dis posed to hold doors and other swinging members in various positions, 1t partlcularly is adapted to hold a door in wide open position. It is desirable with many doors and particularly garage doors, that the same be held in open position after having been opened. lVith garage doors this is important, for, if the door swings toward closed a position it is apt to be struck by an incoming or outgoing vehicle.

It is an object of this invention, therefore, to provide a simple and very efficient door holding means adapted to be operated by the door to hold the door in fixed position.

It is a further object of the invention to provide such a member together with a securing means for holding the same in position with the door held therein and a means adapted to be manipulated by the operator for releasing said securing mechanism so that the door may again be closed.

It is more specifically an object of this invention to provide a door holding. means comprising a base which may be made of a strip of flat iron having secured thereto and pivoted thereon, a bell cranklever having arms with door engaging means thereon, which arms are adapted alternately to be disposed in upstanding or depressed position, said base member carrying a stoptoward and from which said arms swing, together with securing means for holding the arm remote from said stop in upstanding position with the door between the same, and said stop, and means for releasing said securing mechanism so that said bell crank lever may be swung to permit said doorto be closed. v

These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to the line 3-3 of Fig. 1, as indicated by the ar-- rows.

Referring to the drawings, the device comprises a base nember l adapted to be secured to 'or'set' into the floor, and while this base member maybe made in various ways, in the embodiment of the invention illustrated, the slameis shown as formed of a flat strip preferably of metal having one end 4 reversely bent and extending parallel to the horizontal portion of the strip, the end 4 then being bent substantially at a right angle to extend vertically. Attaching screws or bolts 5 extend through holes in one end of strip 4E and through the other end and its parallel portion et said screws being adapted to hold the base member in position. The vertical arm 43 has secured at its top a stop member 6 which may be of resilient material and which is held in place bya headed and nutted bolt 7 A U-shaped or channelshaped plate 8 having vertical side portions is secured to the base l by suitable rivets. A bell crank member 9 having arms 9- and 9 is pivoted on a pivot member 10 extending transversely through the side portions of spectively which may have rubber or similar yielding material at their peripheries. The members 11 and 11 are spaced a somewhat greater distance than the width of the door 12 and are adapted to be respectively engaged by the sides of said door so that the arms 9 and 9 alternately. areswung to upstanding or depressed position. The axis of member 10 is substantially horizontal and parallel to the door engaging surface of stop 6. A plate or sear spring 13- is secured to the top ofbase l by'a headed and nutted bolt 14; and extending between the sides of plate 8 and beneath member 9. This spring isun- ,der tension and engages the bottom surface ofarm 9 when said arm is depressed so that member 9 is heldyieldingly in such position. Said member 9 is also provided with a ledge or shoulder; portion 9 fWh-ich engagesthe end'of spring 13 so that 'wh'emarm 9 is' depressed the member 9 is in the position illustrated in full linessin:Fig.111,?withitheiidoor 12 between arm 9 and the stop 6, said member 9 is effectively fastened Orsecured in position and cannot be swung. A rod 14L extends through the sides ofplate 8 andis ,4 journaled therein, said rod being outv away to'form afl at sur'facela adaptedltoengage the top of springl3,said1rdd extending betwe'enisai'd spring and member 9. The rod lat-isreverselybentat the sideof plate 8 and base 4 an'd'has its other end extending 15 over base hat the outer 'sideof plate -8, said latter end being cutaway, as shown'at l4" and. adaptedto engage'thetop ofbaset to "limit the" turning movement of rod 14. It will be .-noted that the cutaway-surface 14: is eccentric to" the horizontal axis of rodll l. ,The1-nember"9'when swungtothe position shown in dot-te'd lines in 1, also engages f' the top of spring13' and is yieldingly'held by said "spring in such position.

"In operation, the device willbe placed in will bein. thepos'ition shown in dotted lines inF ig.]1"with the arm?) and its roller 39 l1;yieldinglyheld in upstandingposition. -The a rm"9 willthenbe depressed andiits roller 1'1 will be low enough for the door i to'passiov'er the'same. As the door swings to its open position'therefore, it will engage the rollerll'011Larmi'9 an'dkarm"9 will be dexpressedagainst the! tension of spring 13 and army 9* willbe swung to -=up"standing position.

""Th'edoor" engages stop 6 and when'between "said-stop1andthe rollerll 0narin 9 the,

shoulder?"engagesthe end of springil3. "The member 9 thenv cannot 'be swung back- "wardly and the door is held'inpos'ition betyve'en reller ll and r arm 9" and the "stop Y"6. Vhen it-is desired toaa-gain close the ".door the op'er'ator "merely" steps on the bent "orjbight,jportion of the ro'd"14. Thistrod .is' thus oscillated in plate 8 and the fiat :surface 14* which is eccentric presses-"down ,onf'the'spring 13 and -'-moves the-end of '"saidqspringr out of engagement with shoulc'l'erSF. Thedoor 12tcan'then be swung "towards closed? position and (arm 9 will "againjbedepressed and arm: 9 brought to "upstanding 'position.
